This invention relates to a device through the medium of which ashes may be deposited.

in a bucket without scattering the ash dust about the furnace room, and has for one of its 5 objects to provide a device of this character which shall embody a casing or cabinet for the reception of the ash bucket, a flue establishing communication between the casing or a cabinet and the chimney, and a door located in the casing or cabinet above the ash bucket and normally held closed by a spring, the door being mounted to open inwardly under pressure applied thereto by the toe of theash' shovel so as to permit the ashes to be removed from the furnace and deposited in the bucket tively little floor space. a 4 y The invention is hereinafter fully described and claimed, and illustrated in the accom panying drawing, wherein: Figure 1 is an elevational view illustratlng the ash dust eliminator mstalled in a furnace room, r V 1 Q Figure 2 1s a View partly in. rear eleva tion'and partly in vertical section of the ash dust eliminator, and r v v 1 Figure 3 is a view partly in side elevation and partly in vertical section of the ash dust eliminator.

Referring in detail to the drawing, 1 designates a boiler or furnace of the type usedfor domestic heating, 2 the smoke pipe of the boiler or furnace, and 3 the ash dust eliminator.

The ash dust eliminator 3 comprises a casing or cabinet 4 which is of polygonal con tour in'vertical and horizontal section and which is provided with air intake openings 5 and an airdischarge opening 6. The openings 5 are located adjacent the bottom of the casing or cabinet 4, and the opening 6 is 10-- cated in the top wall 7 of thecasing orv cabpipe 2;

shovel is'inserted in the act of depositing the ashes in the'bucket:

damper 9is closed was not to interfere with 1927. saaimjisasai,

ineti TA flueTS whiCh is provided with a damper'9, etxtends from the opening to the smoke pipeflQ. If-desired the'flue 8 may be arranged :to communicate directly with the chimney. iA'cloupling 1O establishes com munication between the flue S and the smoke The casing or cabinet 4 is adaptedfor' the reception ofthe ash bucket 1l, and to permit the buckettobe placed therein or removed there from the casingfor' cabinet is provided in one of its lateral side's withthe door 12 -which is supported by hinges 13 and provided with a catch 14. 1 The upper portion ofthe front wall of the cabinet orfcasingi4 inclines upwardly and rearw ardly, as shown-at 15,'and said portion is located'above the" ash bucket 'llvand provided with an opening'through which the 0 The opening in the, cas-- ing or cabinet portion 15 is closed by a door 16 which is he f nally supported. inclosed-position by spring hinges 17. These hinges are secured to the loweredge of the door 16 and.

to the casing or cabinet portion 15 immediately below the opening in said portion. The hinges are positioned on the inside of the casing or cabinet 4, andthe door 16 is provided at its inner side witha flange 16, which surrounds the same and contacts with'the inner sideof the casing orcabinet portion 15 to limit-the closing movementof thejdoor under the influence of the spring hinges 17. The Y flange 16 also'prevents dust'from escaping from'the casing or cabinet 4 around the door 16. The rear wall of the casing or cabinet 4 I is provided with a window 18 in order to en-' able the attendant to ascertain the amount of ashes in the bucket 11 without opening either the door 12 or the door 16.,

From the foregoing and accompanying drawing, it should be apparent that when the damper; 9 is opened, air circulates upwardlythrough the casing orcabinet 4, with v the result that the dust raised while deposit- 5 ing ashes inv the bucket 11 will be carried into the chimney by Way of the flue 8. When the ash dust eliminator is not in use, the

the draft through vthe boiler or furnace 1. As the door 16 is yieldingly supported in 1" closed position, and as it will open inwardly on the application of an inwardly directed pressure thereto, it may be opened through the medium of a shovel during the act of inserting the shovel into the casingor cabinet 4 for'the purpose'of depositing ashes into the bucket 11. In use thereof, the ashes may be removed from the boiler'or furnace 1 and de f posited inthe bucket 11 by a single act and without releasing the shovel, and this-may be done easily and quickly and without'agitating the ashes sufficiently to cause dust to rise therefrom.

It should be understood that the drawing is merely illustrative and doesn'ot pretendto give exact proportions. Furthermore, the said drawing is illustrative of a preferred construction, it being my expectation that vvariouschanges and modificationsmay be made without departingfrom the spirit and scope of my invention,

What is claimed is I An ash dust eliminator comprising a oasing adapted to receive a receptacle and providecl adjacent its bottom with air inlet openings, an inwardlymovable door in a wall of p the casing, said door inclining upwardly and rearwardly, hinge'means adjacent the lower edge of the door-securing it to the casing, and spring means normally holding the door in closed position and urgingit thereto, said door being of a; size and so arranged that a shovel may be placed against the same in p v emptying ashes into the receptacle to control its openingand closing movement.

' In testimony whereof Iaifix my signature. 7
